No packets are captured when i try to find out http traffic (tcp port 80). Althuogh I can find them when I capture all packets (e.g. without any capture filter), applying display filter.
I ran Wireshark as administrator but the problem remained.
Windows 7 Wireshark 1.6.5
Thanks in advance

If you do see HTTP packets when you don't use a capture filter and you don't see HTTP when you do use a capture filter, then the capture filter filters the HTTP packets out. This usually happens when traffic is being encapsulated. Depending on the encapsulation type, you need to extend the capture filter:
If these do not work for you, please update this question with the full (text) output of 1 HTTP packet to check what encapsulation you are encountering.
